HENRY W. BRETT, OF BOSTON, MASSACHUSETTS.

CEMENTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 479,699, dated July 26,1892.

Application filed April 23, 1892. Serial No. 430,383. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY W. BRETT, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Machines for Cementing,of which the following is afulL'clear, and exact description.

The tops of boots and shoes have their top and front edges folded over ashort distance and secured by cement; and the object of the presentinvention is to provide a machine for applying on one side of the topsof boots and shoes, at and along the edges,'a cement,preferably made ofindia-rubber, in a simple, practical, and expeditious manner; and theinvention consists, in combination with a receptacle for holding thecement or other suitable liquid adhesive material, of mechanism soconstructed and arranged as to automatically take up some of the cementand apply the same to the top of the upper of the boot or shoe or otherarticle to be cemented, all substantially as hereinafter fullydescribed, reference being had to the accompanying sheet of drawings, inwhich is illustrated a machine constructed in accordance with thisinvention.

Figure l is a plan view of the machine. Fig. 2 is an end view. Fig. 3 isan end view opposite to Fig. 2. Fig. 4 is a vertical crosssection online 4 4:, Fig. 3.

In the drawings, A represents a receptacle for the cement or otherliquid adhesive material, resting on legs B, which are adapted to besecured to a suitable bench, the receptacle having a cover or fiat top0, secured thereto by pins D, which pass through holes a in the A sidesinto holes I) in lugs d on the inside of the cover, as shown moreparticularly in Fig. 2, allowing the cover to be easily removed whendesired to fill the receptacle with the cement.

E is a horizontal shaft turning in bearings F in the ends G H of thereceptacle and having secured to it within the receptacle a wheel ordisk J of sufficient width for the purpose of its use, to be describedfarther on, which wheel is of a diameter to project above the cover ashort distance, extending up through an opening K in the cover or top,as shown in section in Fig. 4. The shaft extends out through the end Hof the box, and on its outer end is secured a gear-wheel L. Thisgearwheel L engages with a smaller gear-wheel M, secured to a shortshaft N, parallel with the shaft E and turning in bearings in a bracketP, secured to the side of the receptacle by a screw e. Secured on theouter end of this shaft N is a pulley Q, having acircumferentialgrooveffor a small belt and a crank-handle g, by which to turn it byhand, if desired, and which is turned in the direction of the arrow h,Fig. 2. Turning this pulley Q, the wheel L is caused to be revolved inthe direction of the arrow, Fig. 3.

In using the machine the receptacle is filled .with any suitable cement,preferably an india-rubber cement, at a height above the bottom portionof the wheel, so that the wheel as it is turned will revolve in thecement, to which it adheres on its periphery or circumference, and tofacilitate such the periphery is preferably serrated or groovedtransversely, as shown. The opening K in the cover, through which thewheel J projects, is large enough to prevent the wheel from touching iton its edge and sides, and near the front side, or that part of thewheel which rises from the receptacle, on each side of the wheel, is aplate R, secured to the cover by screws m, their edges n being close tothe sides of the wheel, so that as the wheel is revolved whatever cementis on the sides is scraped of by the plates R and thrown back into thereceptacle and prevented from coming above the cover, while at the frontof the wheel is another plate S, secured by a screw 7' to the cover, itsedge i being close to the periphery of the wheel, the plate beingadapted to be adjusted forward and backward to allow of more or less ofthe cement adhering to the periphery of the wheel, as desired, as it isintended that the cement shall be carried up on the periphery of thewheel, but not at the sides.

T is a rock-shaft adapted to rock in bearings in two upright arms orbrackets to of the cover, the shaft being prevented from longitudinalmovement therein by a collar 12, secured to the shaft-outside of thebracket, and an arm U, secured to the shaft the other side of thebracket, which arm extends backward beyond the receptacle and has apitman-rod w secured at its outer end, to which rod is connected at itslower end a treadle. (Notshown in the drawings.) This rock-shaft Textends out over the cement-wheel, and secured in a longitudinal slit yin the end of the shaft is a flat spring-presser V, which extends backand is bent under and forward, as shown in Fig. 3, its free end beingslit and divided longitudinally into several strips or fingers, the

' free end of these spring-fingers lying just above the cement-wheel,and when the arm U is pulled down to turn its shaft T it swings or movesthe spring, so that its free ends will lie and press upon the wheel, asshown in Fig. 3 more particularly.

In the operation of the machine the receptacle is filled, preferably,with india-rubber cement and the pulley Q revolved, which turns thecement-wheel J in the direction of the arrow, Fig. 3. The arm is thenpulled down, which moves down the spring-presser V to bear 'upon thewheel, pressing them down thereon firmly. The top of the upper of theboot to be coated with cement is inserted by its edge between the wheelJ and the springpresser V, and as the wheel is turned itis carried alongby it over the wheel between it and the spring-presser, and, beingpressed against the wheel by the spring-presser as it so passes along,its under side, or the side next the wheel, will be coated with more orless of the cement from the wheel, when another top is run through andcoated with the cement, and so on, one after another.

W is an upright post, which screws into th cover under the arm U,against which the arm abuts and rests when pulled down to limit itsmovement and also the pressure of the spring-presser V on the wheel.

The post W can be screwed in or out to adjust its height, and whenadjusted a set-screw thereon is screwed down on the cover, which setsthe post and preventsitaccidentally movlug.

At the right of the wheel J is a plate B, which is in line with one sideof the wheel and is attached to the bent portion of a horizontal arm orrod 0, arranged to rock in the two brackets u, and is secured frommovement by a set-screw E. This plate serves as a guide to the edge ofthe boot-top as it is run through the machine to regulate its movementtherethrough, so that the under side of the material will be covered inthe right place with the cement.

The front plate S has a central longitudinal slot a',through which thescrew b passes, securing it in place, but so it can be moved fartherfrom or nearer to the wheel, accord ing as itis desired that more orless cement shall be left on the wheel-periphery for its deposit on theboot-top, as desired.

On the rock-shaft T is a spiral spring F, secured by one end to therock-shaft arm U and by its other end to the bracket to, which acts whendownward pressure is relieved upon the arm to turn the shaftsufliciently to raise the spring-presser V from the wheel J when not inoperation.

Back of the wheel J is secured by a screw e to the cover a strip G,which extends up and just over the wheel, as shown in Figs. 1 and 3,which serves as a guide to move the boot-top, after being cemented, awayfrom the wheel to prevent injury thereto.

The spring-presser can be all in one piece in lieu of several fingers;but a series of narrow spring-fingers is preferable to use, as by such apressure will be exerted upon all parts of the material'to insure thatwhatever irregularities there may be in the thickness of the materialits desired surface will surely be fully covered with the cement. Thepulley can be turned by hand or by belt, as desired.

Having thus described my invention, what I claim is 1. In combination, areceptacle for cement or any suitable adhesive material, a wheel securedto a revolving shaft adapted to turn in said receptacle, and aspring-presser secured to a suitable support and arranged to bear by itsfree end on the periphery of the wheel.

2. In combination, a receptacle for cement or any suitable adhesivematerial, a wheel secured to a revolving shaft adapted to turn in saidreceptacle, and a spring-presser comprising a series of spring-fingerssecured to a suitable support and arranged to bear by their free ends onthe periphery of the wheel.

3. In combination, a receptacle for cement or any suitable adhesivematerial, a wheel secured to a revolving shaft adapted to turn in saidreceptacle, a spring-presser secured to a suitable support and arrangedto bear by its free end on the periphery of the wheel, and a guide-'-plate for guiding the article through the machine.

4. In combination, a receptacle for cement or any suitable adhesivematerial, a wheel secured to a revolving shaft adapted to turn in saidreceptacle, a spring-presser secured to a rock-shaft and arranged tobear by its free end on the periphery of the wheel, and an arm securedto said shaft connected to means for operating said arm, for the purposespecified.

5. In combination, a receptacle for cement or any suitable adhesivematerial, a wheel secured'to a revolving shaft adapted to turn in saidreceptacle, a plate secured to the cover on each side of the wheel, anda plate secured to the cover in front of the periphery of said wheel,for the purpose specified.

6. In combination, a receptacle for cement or any suitable adhesivematerial, a wheel secured to a revolving shaft adapted to turn in saidreceptacle and having its periphery serrated or grooved transversely,and a springpresser secured to a suitable support and arranged to bearby its free end on the periphcry of the wheel.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
